Arsenic Contamination of Soil and Water and Related Bio-hazards in Bangladesh
نویسنده
چکیده
Shallow groundwater is heavily contaminated with arsenic in Bangladesh. The results of a total of 77 samples in two studied upazilas Daudkandi and Begumganj showed elevated levels of arsenic contents in tube well water (range: 0.29-0.71 ppm, n = 6), soils (range: 5.64-29.47 ppm DW, n =16), human scalp hair, (range: 2.41-14.91 ppm DW, n = 8), kachu (range: 0.11-3.89 ppm FW, n = 5), water spinach (range: 0.091-2.032 ppm FW, n =6), potato (range: 0.02-1.86 ppm FW, n = 5), danta stem (1.41 ppm FW, n=1) and paddy rice (range: 0.02-3.40 ppm DW, n = 13). No significant level of arsenic was found in balsam apple (n=5), pointed gourd (n=6), ladies finger (n=1) jute leave (n=1) and catfish (n=4). Extensive withdrawal of arsenic contaminated groundwater contaminates surface soils and plants and thus affects the food chain. 138 Fate of Arsenic in the Environment

Assessment of Arsenic Contamination of Groundwater and Health Problems in Bangladesh
Excessive amounts of arsenic (As) in the groundwater in Bangladesh and neighboring states in India are a major public health problem. About 30% of the private wells in Bangladesh exhibit high concentrations of arsenic. Over half the country, 269 out of 464 administrative units, is affected. Similar problems exist in many other parts of the world, including the Unites States. This paper presents...

متن کاملArsenic Tracking in Iranian Rice: Analysis of Agricultural Soil and Water, Unpolished Rice and White Rice
Since rice is a staple food most consumed world-wide, there have been increasing health concerns regarding exposure to arsenic through rice consumption. Several studies have reported the accumulation of arsenic in rice grains cultivated in regions with elevated levels of arsenic in groundwater or contaminated soil. Therefore the principal aim of this study was determining the amount of arsenic ...
